Secrets of Atlantis slot from NetEnt

Secrets of Atlantis slot from NetEnt
According to some legend, Atlantis is an underwater city somewhere at the bottom of the ocean. Its existence has never been proven, and its alleged location is also a mystery. What’s not a mystery is that NetEnt used this mythical, aquatic theme as the base of the Secrets of Atlantis slot, and they did a great job with the graphics and serene soundtrack, as we are used to expecting from them.

It doesn’t come with Free Spins, but the Nudge Wild Mermaid and the Colossal Symbols Re-spins have the same high potential of big payouts. Go on your own treasure hunt and find up to 320 000 coins in this flooded city while spinning the reels at this medium volatility slot. With an RTP of 97.07%, it’s surely worth exploring.

Personal testers’ opinion abouut Secrets of Atlantis slot

  • You can take a risk and try completing the bonus requirements at the Secrets of Atlantis slot (it scored 5.95 out of 10 wagering points), but overall, it doesn’t keep the balance all that well. The probability of a hit in the regular spins reaches 23.50%. Up to 61% of the total prize pool will be reserved for their payouts. The rest is set aside for the Colossal Symbols Re-spins, which statistically are launched every 32nd spin (3.10%). Our maximum payout during the test sessions was 256x total bets, but only 120x was what we obtained maximum during the Colossal Symbol Re-spin. 

Review and recommendations by the testing team

  • Even for NetEnt, this is an unusual slot, with its two-way payout gameplay and the omission of Free Spins.
  • It can easily give 5-10 spins in the regular spins without any wins and then reward you with a tiny payout equal to your bet. One big winning is tough to land in the usual spins, despite the nudge Wild Mermaid’s efforts to help you out. 
  • The Colossal Symbols Re-spin feature is launched with low frequency, but when they are finally triggered, most of the time, they are part of a series. But don’t expect colossal wins every time. You’ll see the 3 center reels being highlighted, and automatically your heartbeat starts to go up. Then it’s time for the Colossal Symbol to stop at some point and show itself. And there you go! It’s exactly not the one you’re waiting for. It doesn’t often match with reels 1 and 5. But if at least one symbol on either side is identical to the Colossal symbol, the rewards will be significant. They can reach up to 30x-50x total bets. When a few identical symbols land on reels 1 and 5, massive winnings up to 400x the bets, can come your way. On average, the winnings of this bonus feature range around 150x-200x total bets.
  • When the Colossal central symbol is highlighted again, it will Re-spin again, resulting in truly massive payouts. During our tests, we once scored the unbelievable number of 5 Re-spins in a row!
  • If you play with real money, make sure your bet balance is high enough because the slot usually doesn’t give the Colossal Symbols or Mermaid at the start of the session.

How to win at the Secrets of Atlantis slot machine? (Conclusion)

  • We keep on repeating the same wise first step before investing real money: Test the slot in the DEMO version. 
  • The slot is recommended for playing with real money due to the high RTP. The biggest potential lies in the Colossal Symbol Re-spins and Wild Nudge. They come around with a low frequency, which explains the big bankroll needed since the Secrets of Atlantis slot doesn’t always give bonus features at the beginning of the session. 
  • Changing the denomination here doesn’t change the cycle of the slot, according to us. We suggest playing with smaller stakes continually and having a bet balance of around 200 bets at your disposal.
  • We can recommend this slot for the bonus hunters among us, but we would advise you to determine in which mood the slot is in before going all in.

Where to play?

  • The best place in Canada to launch the Secrets of Atlantis slot for free or real money is Fastpay Casino. They offer over 5300 casino slot games as well as super-fast and no-hassle withdrawals. You will be pleased with their bonus program and a VIP bonus program for all loyal players.
